摘要

目的初步了解1～2月龄中耳功能正常婴儿的宽频声导抗声能吸收率值特征。方法纳入足月生产、发育正常的2月龄内婴儿23例41耳(其中1月龄12例23耳，2月龄11例18耳),在组合听力测试判定中耳功能正常后，进行宽频声导抗测试并比较测试结果，分析声能吸收率特征。结果 (1)分别比较1月龄和2月龄婴儿左右耳间的声能吸收率，差异无统计学意义(P>0.05);(2)2 000 Hz左右的声能吸收率最大；(3)1～2月龄婴儿的声能吸收率在低频226～545.25 Hz有统计学差异，2月龄组的声能吸收率小于1月龄组(P<0.05)。结论 1～2月龄中耳功能正常婴儿高频声导抗声能吸收率在低频有统计学差异，印证了随着年龄的增加，中耳系统逐渐由质量为主转为劲度为主；对于1～2月龄婴儿，宽频声导抗更利于了解其中耳功能。
